I just played 5 games and it is already starting to devolve into the same picks every game.
Jax and Sona so far are just plain ridiculous. They should be removed.
Malzahar is the most oppressing thing as well. He just ends the game before we can have fun.
Fiora has a 2.8 second riposte CD. It's insane.
Wukong has perma stealth and there isn't an effective way to counter it.
I can go on and on.
